The current study measured the influence of milk subclinically infected glands by different bacteria species on cow’s milk. effects bacterial infection or inflammation gland yield were related to that caused infection. volume inflamed from was significantly lower (P<0.001) for previously Escherichia coli (PIEc) and those with Streptococcus dysgalactiae. Coagulation properties, rennet clotting time (RCT) curd firmness (CF) also depended causing RCT values all longer CF than healthy ones. Moreover, in whole milk, not proportional Calculation predicted 40% dry matter weight (PCW) cow level, including alone, showed 10 13 PIEc cows, presence affected gland’s resulted a PCW value. Likewise, 7 20 cows S. dysgalactiae had negative delta values. Unlike latter bacteria, CNS increased, although magnitude glands. No correlation found between logSCC (healthy glands) PCW.
